This genus, which has long stood in our cabinets with Dr. 

 Leach's MS. name Rhysohius, has been pubhshed with the 

 name we have adopted. The Baron Dejean has included 

 Nitidula litura Fab., in which he has followed Schonherr; 

 but it appears rather to belong to the genus Scymnus of 

 Herbst. 



1. C. pectoralis Fab. Panz. 78. 5. — rosea Marsh, j). 123. 25. 

 An insect we frequently meet with on grass and plants by 



the sides of ditches and on marshes during the spring and 

 summer. 



2. C. scutellata 



Was not known to inhabit Britain until Mr. Joseph Spar- 

 shall and myself, in an entomological excursion to Horning 

 marshes in September 1819, found several under the bark of a 

 dead tree ; but in the month of March of the present year it 

 was taken upon a gate post in Plaistow marshes by Abraham 

 Cooper, Esq. 



This is the first example we have given of Latreille's section 

 Trimera, with all the tarsi 3-jointed, it consequently associates 

 with the family Coccinellidce, an appellation that we prefer to 

 Aphidiphagi recently employed in the " Families Natiirelles" 

 because in forming the Linnaean genera into families we can- 

 not do less than retain the names of that illustrious naturalist ; 

 and we cannot do better to promote the extensive and philo- 

 sophic views taken of entomology at this period, than by 

 making names long established and universally known, the 

 stepping-stone to those which have been but recently intro- 

 duced. 



For a specimen of the plant figured, Dentaria bidbifera 

 (Bulbiferous Coral- wort), we are indebted to Mr. G. Charl- 

 wood, who gathered it the beginning of last May at Black- 

 wood's old locality, Harefield Park, Middlesex.
